Symmetric Wrapped Key Exchange

Symmetric wrapped key exchange uses a pre-shared symmetric key for key exchange. The wrapping algorithm is predefined and associated with the wrapping key.

This scheme is identified by the string SYMMETRIC_WRAPPED.

Key Request Data

keydata = {
  "#mandatory" : [ "keyid" ],
  "keyid" : "string"
